摘　　要：描述了层状电气石岩的物理特征、岩性组合特征,分析了其化学成分,作了理论研究,确定了该层状电气石岩为火山喷气—沉积变质成因,形成于海底火山喷气—沉积构造环境中,其原岩是一套富硼镁的泥铁质—硅质岩石。它的发现对在该地区找矿具有重要指导意义。The physical properties and lithological association characteristics of the bedded tourmaline are described, theoretically, making further study. Thus, it is determined that the bedded tourmaline belongs to volcanic exhalation-diagenic metamorphic origin, forming in the submarine volcanic exhalation-sedimentary tectonic setting, its primary rock is a set of the rich B-Mg argillaceous iron-silica rock. Its discovery has an important directive function for ore-search in this area.
